The earpieces are slightly larger than the 270s. The top fit great over my breast (form fitting but not tight) but the mid section perfectly loose fitting for me. Nice to see a company that has been around for decades and is still able to provide a good product at a good price. Great shoes and colour. Overall very good quality! When you press the infinite button it should start to play the same music. I was originally looking at the popular wall rack but reviews indicated it had issues, and the fatal flaw was the hooks were not securely in place and I needed the kids to be able to use it safely. The idea of this appealed to me more in theory than in practice, for a couple of reasons. I just got this item this morning. People with any kind of sound sensory issues.
